Hi Craig
Thanks for your response.
The encoder is 20 bit I believe. (See screenshot)
The downside is that the CSMIO has limited signaling speed, and in any event signaling over 500kHz between controller
and servo drive is DIFFICULT at best there is therefore a practical limit to the resolution beyond which the signaling speed limits the rotational speed.
If my calculations are correct the kernel speed should not be an issue at whatever resolution considering the rpm of the C axis will not need to exceed anything over 100rpm.
If P1-46 does adjust the encoder resolution which has a max value of 40,000. Using this ridiculously high resolution. 40000 x 4 x 100/60 = Kernel speed of 266khz. To get the resolution I require would only need 10,240 lines/rev. So 10,240 x 4 x 100/60 = Kernel speed 68khz.
Please correct me if I'm wrong.
I don't follow you on the zero error window.
